A covalent bond (I’m assuming that’s what you mean)
If the EN difference is less than 1.7, it’s a covalent bond
the answer is c
Explanation:
because c has all elements mixed together
the 2nd one is correct
The option that would most likely increase the rate for a more contentrated potassium hydrogene
:) hope this helps
Answer:
The reaction is shifted to the left.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- When there is a decrease in pressure, the equilibrium will shift towards the side with more no. of moles of gas molecules of the reaction.
- The reactants side (left) has 4.0 moles of gases and the products side (right) has 2.0 moles of gases.
- So, decreasing the pressure will shift the reaction to the side with more moles of gas (left side).
- <em>so, the reaction is shifted to the left.</em>
<em></em>
The molar mass of O2 is 32g/mol. So the mol amount of these O2 is 56/32=2 mol. STP stands for the standard temperature and pressure which means the temperature is 0 ℃ and pressure is 100 kPa. And the molar volume of gas is 22.7 L/mol under STP. So the answer is 22.7*2=45.4 L
